Comcast customers in Pittsburgh and Denver now have an additional option for checking out a flick the day the DVD drops: video on demand. While this probably isn't going to hurt DVD sales — since people who buy DVDs on release day theoretically want to keep them — Blockbuster might take a beating, since rental was previously the only other (legal) option for checking out a DVD on D-day, given that the lag time between a DVD's release and its debut on VOD was about 4-6 weeks. Worse still for rental chains, the price is right at $4 a pop and you don't even have to waste gas money to take the sucker back. – Matt Buchanan
